A pedestrian was fatally struck by a vehicle Wednesday on the Pomona (60) Freeway in Diamond Bar.
California Highway Patrol officers responded to a collision at about 2:15 a.m. Wednesday along the eastbound freeway near the Orange (57) Freeway, according to the agency.
A red Kia was initially believed to have hit a rock along the freeway, but officers at the scene discovered the vehicle had struck a woman, and began administering CPR before pronouncing the victim dead at the scene, according to the CHP.
Officers closed off all eastbound lanes with flares and issued a Sigalert.
The closure was later reduced to a single main lane of the 60 Freeway, although the transition road from the 60 to the 57 Freeway was also closed.
All lanes were reopened by about 6:30 a.m., according to the CHP.
It was unclear why the pedestrian was on the freeway.
